Status of French Guiana

French Guiana is officially known as the Collectivité Territoriale de Guyane (CTG), established on 1 January 2016.
The status of Guyane is prescribed by Law No. 884, adopted on 27 July 2011 and published the next day in the French official gazette, No. 173, p. 12,821 (text).

The flag of the Territorial Collectivity of Guyane is white with the collectivity's logo.
The Territorial Collectivity of Guyane was inaugurated on 18 December 2015 in Cayenne ((photos), Rodolphe Alexandre being elected its first President. The flag was inaugurated the same day; flags were hoisted on the stand behind the speaker as follows, from viewer's left to right: European Union, Suriname, France, Brazil, Guyana, and CTG.

The logo of the Territorial Collectivity of Guyane was unveiled on 29 April 2015. A call for proposals yielded 97 submissions. Along the five submissions by an ad hoc commission, Carole Mathée's design was selected by a public vote. The four other finalists were Mathieu de Rivoyre, Pierre-Laurent Kichenama, Thierry Chantel, and Morgane Gonidou.
Carole Mathée explained the logo as follows (Territorial Collectivity of Guyana):

Guyane, the creative spirit.
The logo represents Guyane as a whole, proud of its major assets, which are the base of its development. The new logo is an evolution of the two logos of the former collectivities (colours). The whole is self-styled dynamic and serious. Adaptable ad libitum for the sake of communication (logo, poster, t-shirt, website, actions...), the logo can also evolve in the next decades, being easy to transform.

Elements.
The map of Guyane has been kept for geographical identification. The outline has been stylized to represent opening to the future, as well as the potential, skills, projects and ambitions of Guyane.
The stylized bow and arrows, ready for launching, are a nod in the direction of the spatial industry. Each of them represents assets required for projects and action.
These elements refer to Amerindian peoples, the first inhabitants of the territory who aspire to recognition. The logo is a tribute to their history and aspiration, as well as to their willingness of empowerment.
The black writing, simple and clear, names the collectivity, highlighting the word "Guyane".

Colours.
The set of colours alludes to the Tembé art*, as a reference to the Maroons, other autochthonous peoples aspiring to visibility.
Green (map and bow) represents the exceptional natural environment, protective, provided its intrinsic properties are preserved, and its services (agriculture, leisure, forestry, health, well-fare...).
Red represents the men and women living on the territory, as the first resource (knowledge, generations, culture, traditions, diversity, sustainable responsibility) of a true land of welcome, generous thanks to its living environment.
Blue represents water of any kind (sea, rivers, rain, water production...) as a nourishing resource (fishing, leisure, electricity production...).
Yellow represents the underground resources, either exploited or potential (gold washers, traditions...).
Black represents the promising resources for the future, such as oil (technological innovation, economical development, skills...).

*Tembé is the sculpture art developed by the Boshinengue, the Maroons of Guyana. Tembé is better known as Boni art, named for one of the six Maroon tribes that fled Suriname to Guyane, crossing river Moroni, in 1713-1715: Saramaca, Hatawai, Quinti-Matanai, Boni (Aloukou), Paramaca and Aucaner (aka Youca or N'Djuka). Their specific art was recognized and popularized by the ethnologists Richard and Sally Price, the geographer Jean Hurault and the historian of Guyana Pierre Servin. While some scholars consider the Tembé art as locally borne in the 19th century, Pierre Servin highlighted the influence of the Afro-Egyptian art.
The master of Tembé is Antoine Aouegui, aka Lamoraille (b. 1944). active since 1983 and president of the Mama Bobi association, which aims at the preservation of Tembé as an art, beyond folklore.

Department of Guyane

Flags of the former Department of French Guiana - Image by Ivan Sache, 25 October 2009

The General Council of French Guiana has adopted unanimuously on 29
January 2010 a flag for the department. Unsurprisingly, this is the
flag diagonally divided green-yellow with tyhe red star of the
middle, until now the official flag of the UTG workers' union.
"The upper green triangle symbolizes forest while the lower triangle,
yellow like gold, represents the numerous underground resources. In
the middle, the five-pointed red star symbolizes the socialist
orientation of the country". According to the ad hoc commission, the
meaning of the star should be modified to "the blood in the middle".
Alain Tien-Liong, President of the General Council, said that "the
flag should be hoisted together with the French and European Union
flags".

According to an opponent to the flag, the session of the General
Council took actually place on 22 January 2010; three General Councillors were not present, all from the opposition group (right), but another five
opposition councillors voted for the flag together with the majority.
